Answer:
x=74 degrees
Step-by-step explanation:
OK so for substitution you will be taking away so say you have 5 apples and someone eats 3 you now have 2 apples. so it would be 5 - 3 =2
I hope this helps
Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ( distribute terms in parenthesis by the - 2 outside )
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
Answer:
Vertex (1,-25), Intercepts at (6,0) and (-4,0)
Step-by-step explanation:
Axis of symmetry = -b/2a = -(-2)/2(1) = 2/2 = 1 so x=1 is the equation of line
Plug x=1 into equation y=1-2-24=-25
factor for x-intercepts: (x-6)(x+4)
set them equal to zero: x-6=0 so x=6 x+4=0 so x= - 4
